SGS NSS Testing Report TUV NSSTesting Repopt

Heat treatment

1.Quenching with fire about 860 °C, placed in furnace box

2. After quenching, put into the oil tank to cool from the box furnace

3. After cooling, the first time tempering: tempered at 640 °C and the hardness is controlled at about HRC28-32, the first time tempering cooling is used Water-cooled.

4. Straightening: The outer circle is controlled by 200 um(0.2mm) ;

straightening equipment:

three-roller straightening machine；

hydraulic straightening machine (multipoint straightening)

5. The second tempering removes the hard force, the temperature is about 480 °C, and Keep warm for 2 -2.5hours ; release 80% more or less

In the whole crafts process, there are 2 times remove hardening forces: the first remove hardening force in the heat treatment process, hardening force remove is about 80%; the second remove hardening force in the surface treatment process, hardening force remove is about 90%-95%. Therefore, the piston rod is not easily deformed during use or transportation.
